Hi All,

With Gorizont 17 already dipping low into the southwest, I decided
to see if I could find Gorizont 14 flashing.  I had last observed it
Sept 24, 1998, flashing to magnitude +5 with a period of 87.32
seconds.

Took a little patience, but I found it in Orion to the upper left of
the belt stars.  This is an easy binocular object (I used 8 x 56);
flashes were magnitude +5.5 once every 85.155 seconds.  So
the period has decreased more than 2 seconds in less than
4 months.  Flashes were visible from southern California from
5 UT to 6 UT on 12 Jan.  It was already flashing nicely when
I found it, and clouds cut me off at the tail end, so it could
easily be flashing for 90 minutes or more.  The following elements
are fine for acquisition:

Because of the slow rotation rate, the flashes have noticeable
duration -- perhaps half a second.
